AI Technical Summary

Technical Problem

[0004]1.在移液过程中，由于进液头部会存在残留，为了避免样本之间的相互污染，常采用更换对进液头部进行更换或清洗方式解决，而每次更换进液头部，会显著提高使用成本，并且每进行一次移液操作，则进行一次更换或清洗操作，会花费额外时间，降低检测效率；

Benefits of technology

[0023] Compared with the prior art, the beneficial effects of this invention are as follows: 1. A blood sample bottle containing a pre-treated (e.g., centrifuged and separated) blood sample is transported to the rear end of the blood sample transport mechanism by the blood sample transport mechanism, and a reagent bottle containing a prepared drug solution (e.g., an organic solvent for removing impurities) is transported to the rear end of the reagent transport mechanism by the reagent transport mechanism. The robotic arm drives the first support frame to move, so that the pipetting body takes the blood sample from the blood sample transport mechanism and then feeds the blood sample into the reagent transport mechanism. During the feeding process, the liquid in the reagent transport mechanism is stirred by the stirring component to make the blood sample and the drug solution fully mixed. After a preset time, the blood-drug mixture is aspirated and transferred to the alternating self-cleaning detection mechanism by the pipetting body to realize the detection of blood drug concentration.

Abstract

The application discloses a drug concentration detection equipment, belongs to the blood drug concentration detection technical field, including base station, the multi-station pipetting mechanism, blood sample conveying mechanism, reagent conveying mechanism, automatic head changing mechanism, synchronous cleaning mechanism and alternate self-cleaning detection mechanism are installed on the base station, through the above-mentioned mode, when a group of pipetting units are driven by the mechanical arm to carry out pipetting operation between the blood sample bottle and the reagent bottle and between the reagent bottle and the alternate self-cleaning detection mechanism, another group of pipetting units will synchronously extend into the inside of the cleaning cylinder, the driven type inner cleaning assembly is driven to run by starting the stirring assembly, the all-round cleaning of the inside and the outside of the stirring assembly and the pipetting main body is realized, so that the recycling of the pipetting unit can be realized, the repeated use of the pipetting main body to the sample is avoided, the detection precision of the detection result is ensured, the automatic, high-efficiency pipetting, mixing and detection operation of the sample are realized.
